What are some examples of Hibernate mapping?

Hibernate mapping is used to define how Java objects relate to database tables. Examples include One-to-One, One-to-Many, and Many-to-Many mappings.

Can you explain One-to-Many mapping with an example?

Sure! In a One-to-Many mapping, one entity can be associated with multiple instances of another entity. For example, a 'Customer' can have multiple 'Orders'. You would use annotations like @OneToMany in your entity class.

What about Many-to-Many mapping?

In Many-to-Many mapping, multiple instances of one entity can relate to multiple instances of another. For instance, 'Students' and 'Courses' can have a Many-to-Many relationship. You would typically use a join table to manage this relationship.

Are there any best practices for Hibernate mapping?

Yes, some best practices include using lazy loading for performance, keeping your mappings simple, and using proper cascading options to manage entity states.
